TTC First flight out of Santa Paula Calfornia.

The water temp never got over 120 degrees F. The oil temp never got
over 166 F No oil cooler.  3 gallons of oil. The throttle never got
over 52% The manifold pressure never got over 48 inches of Hg The
blow off valve on the manifold is now set to 71 inches of Hg. We can
reset it to anything up to 100 inches of Hg. The exhaust temperature
never got over 1500 F.

So much for the first flight.
----------------------------------------------------- Static test
tied down. The second chart is going to amaze you if you really know
engines.

Full throttle at ... wait for it........85 INCHES OF MERCURY!!!!!

A piston engine would blow up  and kill everybody within 50 feet of
it.

7200 RPM static tied to my truck. Two strands of half inch nylon rope
that stretches.

All the temperatures are well within limits including the manifold
air temp at only 130 F. Water injection cools it.

This is why we put a blow off valve on the manifold set to 71" of
mercury.

Paul, what was the lambda or airport and 85 inches of mercury?
Also what your charts would be more informative if the ranges were set more realistically for air, oil, and water temperatures. Increase the top of the range to at least 200.
The AFR is probably most critical making sure that you don't go lean at wide open throttle.
Respectfully,

The Motec does a good job controlling it around .72 to .76.

Do you know how to control the variables displayed in Motec i2?

A few like Lambda was deleted in the high pressure data  I have.
I can get the data again out of the airplane and it will be in there.

Does the M800 always sense barometric pressure?
